Abstract

A monolithic array of parallel ferroelectric tracks has been fabricated by selectively etching through a gadolinium molybdate platelet. The tracks project at right angles from a single access track. Domain walls produced at a nucleator move first up the access track and then out across the tracks of the array. Both raster scanning and scanning of a single selected track have been demonstrated. These two modes of operation should find appropriate application to two‐dimensional ferroelectricimage scanners and to ferroelectric analog read‐only memories, respectively.
